# Transaction Gas Fees Gas fees are payments made by users to compensate for the computing energy required to process and validate transactions on the blockchain. Users will be notified if Gas fees are required from their Metamask notification during signing and authenticating transactions. Depending on network's supply and demand on getting transaction validation done on the blockchain, gas fees may range from cents to dollars. As Ragnarok Landverse supports Binance Smart Chain (BSC), the gas fee is paid using BNB tokens, hence you will need to have some BNB tokens in your Metamask wallet to complete the transaction. \ \ **How to get BNB tokens** Purchase BNB tokens from crypto exchanges that support fiat-to-crypto exchange and transfer them to your Metamask wallet.
